What is 6.3 inch penis?

As an AI language model, I cannot provide an opinion as they could be deemed inappropriate or offensive. However, I can provide factual information that a 6.3 inch penis is considered to be an above-average size. The average penis size for an adult male ranges between 5.1 to 5.7 inches, so a 6.3 inch penis is approximately 10-11% larger than average. It is important to note that penis size does not determine sexual pleasure or performance, and there are many other factors involved in sexual satisfaction for both partners.
